IMPROVEMENT IN STEAM-RADIATORS.

Specification forming part of Letters Patent No. 155,986, dated October13, 1874; application filed August 6, 1874. I

To all whom it may concern Be it known that 1, WILLIAM H. SHooK, ofBaltimore, in the county of Baltimore and State of Maryland, haveinvented certain new and useful Improvements in Steam Badiators; and Ido hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art towhich it pertains to make and use the same, reference being bad to theaccompanying drawing and to the letters of reference marked thereon,which form a part of this specification.

My invention relates to that class of radiators in or through whichsteam is allowed to pass to radiate heat; and the nature of my inventionconsists in one or more series of U-shaped perforated pipes orconnections, cast in or otherwise secured to and inside of thefoundation box or casing, in which the condensed steam or water ofcondensation is collected. At the lower end of the U-shaped pipes asmall pipe, 00, is attached, and a series of pipes passing through thefoundation-box,

' as will be hereinafter more fully described.

In the accompanying drawing, Figure l is a plan view of mysteam-radiator. Fig. 2 is a longitudinal vertical section through theline a; m, Fig. 1; and Fig. 3 is a transverse vertical section throughthe line 3 y, Fig. 1, of the same.

A represents a box or casing of any suitable design and dimensions,inthe top of which, and in connections with the U-shaped perforated pipesor connections hereinafter described, are secured one or more series ofr'a' diating tubes or pipes, B B, of the usual de sign. The radiatingpipes or tubes B B of each series are arranged in a row, as shown in thedrawing, the adjacent ends of each pair being connected one to the otherby means of U-shaped pipes or connections 0 0, thereby securing anuninterrupted flow of steam through each row or series, as may berequired. D represents the end of the first pipe in the series throughwhich steam is conveyed from the boiler. Each series of pipes isprovided with one of these steam-inlets D, and in the pipes from theboiler are to be suitable stop-cocks or valves. The end of the last pipein each series opens into the box or casing A, and from this end of thecasing a pipe, G, conveys the water of condensation back to the boiler.

In the operation of this radiator, the steam may be allowed to passthrough as many, or as few, of the series of pipes as required byshutting off the stop-cocks or valves in the inlet-pipes leading to theseries not to be used, and opening them in those leading to the seriesto be used.

The steam, entering (in each series) into the first pipe B, passesthrough the same into the first connection, 0; from thence to the secondpipe, B, and so on, to and through the last pipe in the series, into thebox A, where it is condensed, and, as water, returns through the pipe Gto the boiler.

Any steam that may condense in either of the pipes B will drop into theconnections 0, and from thence, through the perforations or pipes :20,into the foundation box or casing.

It will readily be seen that there is no liability of any watercollecting in either of the pipes, connections, or tubes, to becomefrozen. It all returns directly to the boiler, or to any other suitableplace, at the option of the persons using the same.

- In the ordinary radiators much of the heat is wasted by the steampassing through the tubes uncondensed. I utilize this heat byintroducing tubes a a in the foundation box or casing A, as shown, beinglow down and in the coldest part of the room, and exposed to the actionof the coldest air. The steam in the box or casing is therefore readilycondensed, and the heat that would be otherwise lost is saved.

These tubes at c act as braces, which admit of great simplification inthe construction of the foundation box or casing, being placed at rightangles to each other in the box.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-- The box A,provided with theseries of pipes B, the lower parts of which are provided with smallpipes :20, in combination with a series of hot-air pipes, 61., passing,at right angles to each other, through the box A, serving the purpose ofutilizing the heat, and as braces for the box, as and for the purposespecified.

In testimony that I claim the foregoing as my own I afiix my signaturein presence of two witnesses.
